So as far as superchargers go, which brand (and what stage) should I go for (if I don't want to get a new hood)? Also, what additional parts should be purchased to support the new supercharger? From what I've seen and heard, it would be better if several other fittings and parts were changed to better parts when installing the supercharger.

 

If you are looking for torque get a single turbo. SC's make the least amount of torque when compared to ST and TT setups.

Here is a video of the Vortech SC, Turbonetics ST and APS TT in action.

Information on the Vortech:

It is now CARB LEGAL!!!
Vortech 350Z/G35 EO#D-213-22



The average numbers out of the box:
HP: 375 TQ: 325
I've seen up to:
HP: 420+ TQ: 340+
If you dig around a little more, I think there are some higher numbers but it escapes me now.

It is extremely safe. There wasn't an incident of a blown engine due to this system. If you want more power, a better route would be the single turbo.

KNOWN VORTECH ISSUES

FMU - In some cases, the Vortech kit FMU seizes up. This happens when residue from gas builds up on the washer valve inside the FMU. The result is the washer sticking creating a pressure build up in the fuel line than can pop the fuel line off one of its fittings. Fix is to buy the rebuild kit for the FMU (around $39). Mine did this around 6K miles. Others have done this, but I don't know the mileage. Preemptive solution could be to add fuel additive or high octane gas occasionally. Since I've started this more regularly, the problem has not reoccured.

Belts - Serpentine belt on Vortech tends to "loosen" over time. To keep a good snug fit, a new belt may have to be adjusted 3 or 4 times to ensure there is no belt slippage.

KNOWN TURBONETICS ISSUES:
A lot people are experiencing trouble with the reflash. Can't seem to get the A/F smoothly across the chart.
Aftermarket headers HAS to have the outlet flange in the stock location.
Must use either a y pipe back exhaust (Apexi, Tanabe, Fujitsobo, etc) or a modified dual.

Will post more information later on the other kits. Too lazy now
